1. Why do we classify meteorites?
2. Explain what is meant by primary and secondary processes.
3. What is the fundamental distinction between chondrites and other meteorite types?
4. Explain what is meant by "cosmic abundances".
5. On what does the texture (arrangement of minerals or structure) of an iron meteorite depend?
6. Why are the elements Ga and Ge particularly useful for classifying iron meteorites?
7. What is a "CAI"?
8. Look at Fig. 1.1.7. What do the three lines in the plot represent?
9. Can one meaningfully assign a unique bulk iron content to EH, EL, CI and CM chondrites?
10. What do the H, L, and LL group letters for ordinary chondrites represent?
11. What petrographic type and subtype of chondrites is optimal for studying primary processes? Why?
12. What is meant by a "petrogenetic association" and why do we care?
13. Iron meteorites comprise only 3% of falls, yet nearly half of all finds. What probably accounts for this difference?
14. What do the dots in Fig. 7.3a represent?
15. How many different parent bodies were sampled by the iron meteorites?
16. What are the two major assumptions used for determining cooling rates for Fe-Ni metal alloys in meteorites, and how well are these assumptions met?
17. In which setting or location of a parent body did pallasites form?
